Product Details
Ductile Iron Double Flange Double Eccentric Butterfly Valve Two
Side Sealing AWWA C504
Features:
Arch shape design, stronger ribs on back side, size DN350-1200MM
This can help to BV has a better flow coefficiet when water through
the holes on the disc in fully open position, water will stabilize
the disc and het a better flow coefficeint.
Double eccentric design, less wearing of rubber.
Less compression for rubber, longer life for rubber. When double
eccentric BV in fully open position, the compression of the rubber
is much less than the concentric type of BV. It gives a longer life
time for rubber comparing with double eccentric and concentric BV.
Online repairing by EPOXY:
The special technology can help user to repair the Double Eccentric
Flange Butterfly Valve without taking the valve out of the
pipeline. The user only needs to repair it from the exterior of the
butterfly valve without going into the pipeline. Please consult the
factory and we will show you how to repair the BV when the rubber
seal is damaged.
Seal in both direction.

Company Profile
Alpine Flow Control (SuZhou) Co.,Ltd with major focus in the water
valve design and manufacturing. The Management staff have over 30
years experience in the water valve design and manufacturing,
combined with the high-tech electronics manufacturing experience of
multi-national listed companies. This unique combination of
traditional and high-tech industry management experience and skills
have given us an advantage over the traditional valve manufacturer.
More than 40% of our staff are technical staff with knowledge and
experience in valve and mechanical design/manufacturing...
Proven and supported by on-going quality and reliability test. AFC
has built it’s own in house reliability test laboratory to ensure
that our products not only meet the international quality and
reliability test specification such as the EN-1074-1/2 T-key and
R-key test, but also comply to various international valves
standards and specifications.
We already achieved WRAS certificate in 2011, and obtained FM
approval in early of 2012,
and UL for gate valve. Today, we have got many international famous
certificate for drinking water such as WRAS, NSF, AS, CE on certain
products, and our product range has expended to double eccentric
butterfly valve, rubber disc check valve ,non-slam check valve,
both clean water & sewage water air valve, hydraulic control
valve and penstock and we always focus on water system valves.
In 2018 year, our big plan is developing pressure management valves
which has been proved to be a very helpful tool and economic way to
save the leakage rate with limited investment and get a fast return
in couple months and power savings
In addition, we have a special project team to focus on custom
design and special requirement
